  • Accuracy analysis of digital orthophotos from very high resolution imagery 
    Passini, Ricardo; Jacobsen, Karsten (Göttingen : Copernicus GmbH, 2004)
    The generation of digital Orthophotos now days can be done with aerial, but also very high resolution space imagery. For a real competition the geometric and radiometric quality has to be on the same level. Different ...
  • Analysis and correction of systematic height model errors 
    Jacobsen, Karsten (Göttingen : Copernicus GmbH, 2016)
    The geometry of digital height models (DHM) determined with optical satellite stereo combinations depends upon the image orientation, influenced by the satellite camera, the system calibration and attitude registration. ...
  • Analysis of height models based on Kompsat-3 images 
    Büyüksalih, G.; Bayburt, S.; Jacobsen, K. (Göttingen : Copernicus GmbH, 2018)
    Height models are basic information required for disaster Management. Not in any case satisfying and actual height models are available, but they can be generated by satellite stereo pairs being more precise as InSAR. The ...
  • Characteristics and accuracy of large area covering height models 
    Jacobsen, Karsten (Göttingen : Copernicus GmbH, 2013)
    Large area covering height models are dominantly based on optical and synthetic aperture radar (SAR) space imagery. The vertical accuracy of individual object points determined by automatic matching of optical imagery is ...
  • DEM generation with short base length pleiades triplet 
    Jacobsen, Karsten; Topan, H. (Göttingen : Copernicus GmbH, 2015)
    An image triplet of Pleiades images covering the area of Zonguldak, Turkey has been investigated. The height to base relation of the first to the last image is just 1:4.5 and for the first and the second image 1:9. This ...
  • Optimizing the distribution of tie points for the bundle adjustment of hrsc image mosaics 
    Bostelmann, Jonas; Breitkopf, Uwe; Heipke, Christian (Katlenburg-Lindau : Copernicus Publications, 2017)
    For a systematic mapping of the Martian surface, the Mars Express orbiter is equipped with a multi-line scanner: Since the beginning of 2004 the High Resolution Stereo Camera (HRSC) regularly acquires long image strips. ...
  • Pléiades project: Assessment of georeferencing accuracy, image quality, pansharpening performence and DSM/DTM quality 
    Topan, H.; Cam, A.; Özendi, M.; Oruç, M.; Jacobsen, Karsten; Taşkanat, T. (Göttingen : Copernicus GmbH, 2016)
    Pléiades 1A and 1B are twin optical satellites of Optical and Radar Federated Earth Observation (ORFEO) program jointly running by France and Italy. They are the first satellites of Europe with sub-meter resolution. Airbus ...
  • Problems and limitations of satellite image orientation for determination of height models 
    Jacobsen, Karsten (Göttingen : Copernicus GmbH, 2017)
    The usual satellite image orientation is based on bias corrected rational polynomial coefficients (RPC). The RPC are describing the direct sensor orientation of the satellite images. The locations of the projection centres ...
  • A procedure for semi-automatic orthophoto generation from high resolution satellite imagery 
    Alrajhi, M.N.; Jacobsen, Karsten; Heipke, Christian (Göttingen : Copernicus GmbH, 2013)
    The General Directorate of Surveying and Mapping (GDSM), under the Ministry of Municipal and Rural Affairs (MOMRA) is responsible for the production and dissemination of accurate geospatial data for all the metropolitan ...
  • Systematic geometric image errors of very high resolution optical satellites 
    Jacobsen, K. (Göttingen : Copernicus GmbH, 2018)
    Very high resolution optical satellites are imaging the object space by a combination of CCD-lines in one direction and by time, speed and satellite rotation in the other direction. The combination of the CCD-lines usually ...
  • Temperature Induced Fracturing of Rock Salt Mass 
    Staudtmeister, Kurt; Zapf, Dirk; Leuger, Bastian; Elend, Marc (London : Elsevier Ltd., 2017)
    During the operation of gas storage caverns in rock salt mass the internal pressure changes during filling and withdrawal phases. Additionally temperature variations occur versus operation time. During withdrawal phases ...
